如何从 PHP curl 解码二进制响应

Question

curl -vvvv -k -s -X POST --header 'Content-type: text/xml;charset="utf-8"' --header 'SOAPAction: vend' -u 'USER':'PIN' -d "<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\"><soapenv:Header/><soapenv:Body><vend xmlns=\"http://host.vim.services.co.uk/xsd\"><sequence>6922343</sequence><origMsisdn>xxxxxxxxxxxxx </origMsisdn><destMsisdn>xxxxxxxxxxxxx</destMsisdn><amount>1000</amount><tariffTypeId>1</tariffTypeId></vend></soapenv:Body></soapenv:Envelope>" https://xxx.xxx.x.xxx:443/modlue/services/TargetOne ; echo;

上面的 curl 请求让我得到了下面的响应（在终端中）

但是使用 PHP curl 它只输出

string(792) "00000000031060.002347064058107 23480320303031Sequence Number Check Failed2020012312555188502475422FAILED8076922343" with header informtion `"HTTP/1.1 200 Content-Type: text/xml;charset=UTF-8 Content-Length: 656 Date: Thu, 23 Jan 2020 12:20:02 GMT Vary: Accept-Encoding"` 

如何获取剩余的内容并从 xml 响应中读取相应的值？

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"><SOAP-ENV:Body><xsd:vendResponse xmlns:xsd="http://xxxxxx.xxx.xxxxx.xx.xx/xxx"><xsd:sequence>0000000001</xsd:sequence><xsd:statusId>301</xsd:statusId><xsd:txRefId>2020011515245375604706230</xsd:txRefId><xsd:origBalance>0.00</xsd:origBalance><xsd:origMsisdn>12345678910112 </xsd:origMsisdn><xsd:destMsisdn>12345678910112</xsd:destMsisdn><xsd:responseCode>0</xsd:responseCode><xsd:responseMessage>Insufficient Airtime</xsd:responseMessage></xsd:vendResponse></SOAP-ENV:Body></SOAP-ENV:Envelope>

编辑这是我用来发送请求的 php 代码。 但我希望能够以 XML 的形式获取响应，然后提取 XML 的内容，如 txrefid、响应和消息。

$request = "<xml>Request</xml>";
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL,"https://xxx.xxx.xxx.xxx:443/request");
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $request);
    curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
    curl_setopt($ch, CURLOPT_USERPWD, 'username:password');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
    curl_setopt($ch, CURLOPT_MAXREDIRS, 10);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array(
        'Content-type: text/xml',
        'charset: utf-8',
        'action: action',
    ));
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
    curl_setopt($ch, CURLOPT_ENCODING,'');
    curl_setopt($ch, CURLOPT_VERBOSE, 1);
    curl_setopt($ch, CURLOPT_HEADER, 1);

    $server_output = curl_exec($ch);

    $error    = curl_error($ch);
    $errno    = curl_errno($ch);
    if (0 !== $errno) {
        throw new \RuntimeException($error, $errno);
    }
    else{
        var_dump($server_output);
    }
    curl_close ($ch);

Answer 1

尝试从终端发送curl使用的相同标头：

curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'Content-type: text/xml;charset="utf-8"',
    'SOAPAction: vend'
));
